Estimation of Current Distribution by Near-Field Measurement
Approaches to estimate the current distribution on EM source such as antennas and printed circuit board (PCB) by measuring the near-field distribution are demonstrated.These approaches include the matrix inversion method and sampled pattern matching (SPM) method.All of these approaches require accurate near-field measurement and fieid-currcut inverse algo-rithm.Experimental results are presented and compared with the numerical results,confirming the accuracy and performance of these methods.
